* [[Pyuria]]
* Urinary crystals of [[calcium oxalate]], [[uric acid]], or [[cystine]]
* [[Hypercalciuria]]
* Urinary pH > 7  may indicate an infection with urea-splitting bacteria such as:
** [[Proteus]]
** [[Pseudomonas]]
** [[Klebsiella]], and may lead to struvite stones
* Urinary pH < 5 indicates likely formation of [[uric acid]] stones

* May demonstrate the following:
** [[Hydronephrosis]]
** Ureteral dilation
** [[Abdominal aortic aneurysm]]
** [[Cholelithiasis]]
* Safe in pregnancy but may miss small stones
|
* [[Calcium]] - containing stones are radio-opaque
* [[Uric acid]] or [[cystine]] stones are radiolucent
* Plain or KUB (kidney-ureter-bladder) radiograph may determine stone characteristics such as:
** Size
** Shape
** Composition
** Location
** Differentiate between a phlebolith and an obstructing calcific stone
* Stone movement may also be monitored
|
* Most sensitive modality for renal stones
* Can estimate stone density, size and composition
* CT is able to determine pathology secondary to renal stones, such as:
**  Ureteral dilation
** [[Hydronephrosis]]
** Nephromegaly
** Perinephric fat streaking
* No contrast needed and can diagnose other pathologies, such as:
** [[Abdominal aortic aneurysm]]
** [[Appendicitis]]
** [[Pancreatitis]]
** [[Cholecystitis]]
** Ovarian disorders
** [[Diverticular disease]]
** [[Renal cell carcinoma]]
|
* N/A
|
* Intravenous pyelography (IVP) visualizes entire urinary system and is gold standard for the diagnosis of ureterolithiasis
* Renal tomography can determine similar findings as CT, however has been largely replaced by CT
* Nuclear renal scan can determine renal function
